IMPROVEMENT m PosTs FOR TELEGRAPH-S, 800-.

Specification forming part of Letters PatentNG. 5,781, dated September19, 1818.

To all whom it'may concern:

Be it known that I, HENRY.G.-HALL, .ot' Kigkersville, in the county ofLicking and State of Ohio, have invented a new and'useiul improvement inthe construction of telegraph-posts to prevent rotting at the'surface'of the ground into which they are erected, which is described as'follows, reference being had to the annexed drawings of the same,makingpart of this specification.

Figure l is aside elevation of part of a telegraph-post with theimprovement attached. Fig. 2 is a vertical section through the center ofthe same. Fig.3 is aside elevation of amodification of theimp'rovement.Fig. 4 is a vertical section of the same. Y

The nature of .this invention and improve. ment consists in preven tingthe posts supporting magnetic-telegraph wires from rotting at thesurface of the groundxbyforming on their lower ends shanks or tenons andinserting the same into sockets formed in castiron shoes, made flaringand sharp-on their upper or concave ends to allowthem to bedriven intoshoulders on the posts, which are of greater diameter than the shoes, inorder to overhang and protect them andpreventthe water get ting into theshoes at the joints, said sockets or eoncavities beingv made of greaterdepth than the length'of the tenons, in order to leave spaces betweentheir bottoms and ends of the tenons after the shoes are driven on thesame, and thus allow them to be driven farther on when required. j

The telegraph-post A, Figs. 1 and 2,-has a circular tenon, B, formed onits lower end, which is inserted into a corresponding socket formed in acircular shoe, (J, bound near'its upper end with. a fillet or band, E,for strength- ,enin g the same. The shoe is made flaring and.

sharp at its upper or concave end, E, and is driven on the tenon orshank of the post by percussive foreeapplied to its lower end, orin anyconvenient manner, until the-said flared. and sharp edge penetrates theshoulder formed by the tenon suflieie'ntly far to secure the post andshoe firmly together and form a barrier to prevent the entrance of waterbetween'the socket and tenon, the projecting shoulder s also assistingin this last-mentioned object, as

before stated. After the shoe is firmly secured similar totho'sepreviously described, and represented in Figs. 1 and 2.

Instead of making the'sh-oes ot'cast-iron, as described, they may bemade of stone or any other suitable material, or of clay molded, dried,

and baked in a kiln, the fillet being cast with the shoe. 7

' I do not claim shoeing the ends of wood posts or poles with honorstone to prevent rotting; but 1 What I do claim as my invention, anddesire to secure by Letters Patent, 'is- The manner of combining thecast-iron or artificial-stone shoes 0 with the'posts A-by casting theshoes with sockets of adepth greater than the length of the tenons Benthe lower endsof the posts to be'inserted into said sockets, and withfillets or bands 1) around the external surfaces to strengthen theconcave ends E, which are also made flaring and sharpso as to'be forcedInto the shoulders s of' the posts, which are to be of greater diameterthanthe shoes'in order to overhang and protect them and to prevent the.water getting into the shoes at 'thejoints.

In testimony whereof I'have hereunto subscribed my name before'twowitnesses this 5th day of August,18 4.7.
